A sample was decomposed in the laboratory and found to have 38.67g C, 16.22g H, and 45.11g N.

a)Find the molecular formula of this compound if the Formula mass is 62.12 g/mole.
b)Determine how many H atoms would be in a 3.50g sample of this compound.

Oooo, we're probably not gonna have time for this one lol. It's pretty involved.

Dang that's my last question on this assignment

vshiroky · Answer

I think part A is 62.12 g/mole
                          ----------------------------=2
                     12g/mole + 1g/mole +14g/mole

Ugh, if I write the plan, you'll probably won't get it anyway. Find the moles of each element. Write a fake molecular formula of the compound. Divide each subscript by the smallest amount of moles in the molecular formula.

^^ And it goes on and on lol. It'll take a while.

so my answer is not right then?

ipwnbunnies · Answer

Unfortunately, no.

ipwnbunnies · Answer

Part A asks us to find the molecular formula, which is like H2O for water, or NaCl for table salt.

ipwnbunnies · Answer

Then, we need the formula for Part B.

Crap ok I'm going to fail this portion
